Marine Weather and Tide Forecast for Darwin, CA

DISCUSSION
through Friday.

Latest water vapor satellite imagery clearly depicts a closed low diving into northwestern Mexico with a ridge building over the Great Basin. The N-S pressure gradient induced at the surface will keeping northerly winds around through the weekend. Gusts will be strongest in the lower Colorado River Valley (Laughlin to Needles) today with gusts 20-35 mph. As the low weakens and the ridge amplifies over the coming days, winds are forecast to weaken while temperatures rise gradually. High temperatures are expected to be 2-6 degrees above normal during this time, resulting in quite pleasant conditions across the region. Dry conditions prevail as precipitation chances stay below 5% areawide.

By the end of the week, ensemble and deterministic guidance (both physics-based and AI) continues to suggest a shift to a more active pattern for the western US. At this range, specifics are quite limited and uncertain, but there is good agreement on the presence of a trough near the Pacific coast. What we receive in terms of sensible weather is going to be determined by details such as moisture trajectories and the extent of phasing between the polar and subtropical jets, but the overall pattern appears favorable for precipitation chances, cooler temperatures, and increased winds. The latest 6-10 Day outlook from the CPC aligns with this, having 50-70% odds of above-normal precipitation between November 12th and 16th.
